All of the incidents allegedly happened during Mazo's time as a teacher at Hayden Elementary. Prosecutors say Mazo's pattern of inappropriate behavior at the school stems back nearly three years.

The seven students who came forward said Mazo touched them inappropriately on dozens of occasions. One of the victims was an 8-year-old girl.

Mazo's alleged contact with her alone resulted in 22 separate charges against the teacher who was teaching music at Hayden Elementary up until he was arrested in late April.

Parents have been frustrated by the developments surrounding Mazo's arrest.

"It's unthinkable, you don't think of these things, but you need to, everyone needs to educate their children, and everybody needs to be aware that nobody's going to look out for your child except for you -- the parent," said Logan Cardiner, a concerned parent.

District Attorney Steve Wolfson says the investigation is still open.

"At the end of the day, teachers are like anybody else, there are good teachers and there are bad teachers. In this case we feel we've got a good case against the defendant, and we're going to prosecute him."

Mazo continues to be held on $150,000 bail. If convicted he faces up to a life sentence in prison, but he may be eligible for parole after 10 years.
